drill rig, air compressors and\or booster, rig-up truck, portable water tanks, boom truck, <br />utility trailer, drill pipe lay-down rack, crew trucks, geophysical logging truck and mobile <br />water carriers. <br />Roads utilized in the project will be maintained with water bars and appropriate <br />sedimentation controls as required during the drilling phase. A D9 bulldozer or its <br />equivalent will be used to prepare the road for travel and assist in mobilizing the drill <br />equipment to the drill sites. Additional equipment expected to be used in opening, <br />maintaining, and reclamation may include arubber-tired backhoe, rubber tired grader, <br />roller compactor and attack-mounted excavator. <br />The Gob Vent / De-gas Borehole pads will require reopening of previously disturbed and <br />reclaimed drill roads as previously discussed. The roads would be maintained at a 12 foot <br />width. Movement of equipment across undisturbed land would be kept to a minimum. No <br />brush or tree removal is anticipated on the access route, however if trees are required to <br />be felled, then MCC will contact the USFS District Ranger or his representative to <br />establish payment for the resource. Drill site pads of approximately 120 fr. x 180 fr. will <br />be constructed to accommodate the drill equipment and drill cuttings sump or mud pits. <br />Drill pads will be constructed only as large as necessary. Topsoil will be stripped, <br />stockpiled, and identified with a sign to be used in the reclamation phase of the program. <br />Mudpits to accommodate drill cuttings will be constructed with an approximate size of <br />10' x 20' x 6'. <br />Water for the drilling operations will be pumped to the drill sites from portable tanks <br />using high pressure hose. Alternatively, water may be transported to the drill sites with <br />mobile water carriers. Mountain Coal Company L.L.C. owns water rights for these water <br />resources. MCC may place portable stock tanks near the drill sites and maintain a <br />minimum water level in the tanks to insure water is available for stock and wildlife. This <br />will reduce the risk of stock and wildlife approaching the mudpits for water. <br />DRILLING ACTIVITIES <br />Drilling activities for the proposed gob vent / de-gas boreholes will include mobilizing <br />drill equipment to the sites and drilling and setting approximately 40 feet of 16 inch <br />surface casing into bedrock. The holes will be rotary drilled with a I S inch hole to within <br />150 feet of the B-Seam, then cased with 9 5/8 ID steel casing, then an 8 5/8 inch hole will <br />be drilled to within 50 feet of the B-Seam in the "relaxed zone". It is proposed that one <br />borehole will be drilled from each of the pads to minimize surface disturbance. <br />One vertical exploration hole may be drilled at each of the drill pad locations. Exploration <br />holes will be logged for geophysical parameters and the degas boreholes may be logged <br />as needed. <br />DE-GAS INSTALLATION <br />
